Description
Technical field
Patent of the present invention relates to a kind of equipment blood sample being carried out to microbial culture, especially relates to a kind of automatization blood culture system.
Background technology
In hospital clinical and medical research test, often need to carry out microbial culture to the blood sample of patient.Present blood cultivation instrument is on the market that blood sample is injected flashing lightning magnetic field detector, puts into cultivation instrument and carries out microbial culture.When there being bacterium to exist in blood, the meta-bolites CO of bacterium
2can react with the moisture in flashing lightning magnetic field detector, produce H
+or HCO
3 -ion, in bottle, privileged site places indicator or fluorescent substance, and instrument is provided with color detection means and fluorescence detection device, and when there being bacterial growth in blood sample, proofing unit is reported to the police after capturing information, and alert carries out next step operation.This method advantage can capture bacterial growth information in time fast, but also there is following defect: one is Blood culture bottle complex manufacturing, causes culturing bottle to hold at high price; Two is produce CO in bacteria growth process
2deng gas, the accumulation of these gases can cause increasing of pressure in culturing bottle, when laboratory operation personnel need to operate positive sample uncork, can cause sputtering of blood sample, have certain security risk to laboratory operation personnel.
Summary of the invention
For solving the problem, the invention provides the automatization blood culture system that a kind of technique is simple, cost is low, accuracy is high.
The technical solution used in the present invention is:
A kind of automatization blood culture system comprises thermostat container, sample disk, sample position and Blood culture bottle, it is characterized in that: in described thermostat container, be provided with sample disk, sample disk is provided with sample position, position is placed with Blood culture bottle with sample, and above sample position, corresponding position is provided with gas-detecting device; Blood culture bottle top is provided with detects mouth and thief hole, detects mouth and is connected with described gas-detecting device by junctor.
As preferably, the below of described sample position is provided with swivel arrangement, swivel arrangement is provided with the first magnet and the second magnet, and the first magnet is contrary with the second magnet magnetic.
As preferably, in described Blood culture bottle, be provided with magnetic stirring bar.
As preferably, in described gas-detecting device, be provided with CO
2inductor block and pressure inductor.
As preferably, described thief hole is connected with sampling unit.
As preferably, described junctor center-aisle is provided with filtering membrane.
As preferably, in described sample disk, be provided with at least one sample position.
As preferably, in thermostat container, be also provided with warming apparatus and temperature-control device.
The beneficial effect that the present invention obtains is: the present invention detects mouth and thief hole by arranging on Blood culture bottle, and for positive blood sample, after instrument sample position is exited, bottle external and internal pressure is identical, is convenient to sample and takes out; Connected detection mouth and the gas-detecting device of Blood culture bottle by junctor, detect more sensitive and quick; Arrange swivel arrangement in the below of Blood culture bottle, effectively can accelerate the cultivation speed of Blood culture bottle, culturing bottle production technique is simple, with low cost; When Blood culture bottle puts into the automatic detection that can realize blood after by system.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the connection diagram of the gas-detecting device of Fig. 1, Blood culture bottle and swivel arrangement.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As Figure 1-3, a kind of automatization Blood culture bottle system of the present invention, comprise the thermostat container 1 of a sealing, the sample disk 2 placing flashing lightning magnetic field detector 7 is provided with in the internal space of thermostat container 1, sample disk 2 is arranged at least one sample position 3, the corresponding flashing lightning magnetic field detector 7 in each sample position 3, the position that the top of each sample position 3 is corresponding with flashing lightning magnetic field detector 7 is provided with gas-detecting device 4, is provided with CO in gas-detecting device 4
2inductor block 5 and pressure inductor 6.
Blood culture bottle 7 top is provided with detects mouth 8 and thief hole 9, and wherein detect mouth 8 and be connected with gas-detecting device 4 by junctor 10, thief hole 9 is connected with sampling unit 11, and junctor 10 center-aisle is provided with filtering membrane, for impurity screening or water vapour.The position that the below of sample position 3 is corresponding with flashing lightning magnetic field detector 7 is provided with swivel arrangement 12, swivel arrangement 12 is provided with the first magnet 13 and the second magnet 14, the magnetic pole of the first magnet 13 and the second magnet 14 is contrary, swivel arrangement 12 is driven by motor 16, along with the rotation of swivel arrangement 12, the first magnet 13 and the second magnet 14 rotate and form alternating magnetic field.Blood culture bottle 7 inside is provided with magnetic stirring bar 15, can rotate under the effect of alternating magnetic field, for stirring the blood sample in Blood culture bottle 7, accelerates the growth of bacterium and the spilling of gas in blood sample.
Warming apparatus 17 and temperature-control device 18 is also provided with in thermostat container 1.
Analytical instrument principle of work is as follows:
By the blood sample of patient inject Blood culture bottle 7, junctor 10 is connected with the detection mouth 8 of Blood culture bottle 7, after place it on the sample position 3 of instrument.
Motor 16 drives the swivel arrangement 12 below sample position 3, makes to form alternating magnetic field below sample position 3.The magnetic stirring bar 15 being positioned at Blood culture bottle 7 inside can rotate under the action of a magnetic field, impels blood and nutrient solution mixing.Meanwhile, control the temperature environment in thermostat container 1, make it be conducive to bacterial growth.
